Welcome to Dell Technologies VxRail - How to Series. How to collect vSAN observer logs. Reference Dell Knowledge Article # 503827. This video was created to show how to collect vSAN observer logs to review performance of the current system.
This video presents how to connect to RVC (Ruby vSphere Console). How to start the performance gathering collection. How to gather these files. This procedure can be used to review statistics about VxRail cluster performance and before opening a service request with VxRail support regarding performance issues.
Before you begin you should have gathered root credentials of vCenter and SSO admin password. As a first step we need to log to the vCenter appliance using root credentials. Then log on RVC console using SSO admin account.
We navigate to local host. And then to VxRail data center then choosing "computers" and finally the vSAN cluster. LS can be used to list the cluster names. Once on the correct cluster, we can use the vSAN observer command to launch the tool and start the performance data collection.
Collection is not starting. We can now wait for the time we want to monitor and use CTRL + C to stop the data collection. Once stopped path of the stored bundle is reported on the last output line.
We can now connect to the vCenter using for example, WinSCP and gather the file. These are the main parameters. the observer waits between gathering information in seconds. In the example, it is gathered every 30 seconds. the vSan observer will run. In the example, it will run for one hour total.
If max-runtime is not set, it will default to two hours. a tar.gz bundle with HTML files. If you wish to leave monitor, and not gather logs for later review you can leave generate-html-bundle out of the command.
Thank you for watching.
